DOWNLOAD EBOOKThe existence of the top quark, discovered by CDF and D0 in 1995, has been re-established in the burgeoning dataset being collected in Run 2 of the Tevatron at Fermilab. Results from CDF on the top quark production cross section and top quark mass are consistent with the Standard Model expectations. The well-characterized top data samples will make it possible in the future to probe further for new physics in the top quark sector. This report summarizes recent CDF top quark physics results.

DOWNLOAD EBOOKWe present the recent results on top quark physics and B physics with the Collider Detector at Fermilab (CDF). These results come from analyses using a full data sample at an integrated luminosity of 109 pb−1 cross section in 1.8-TeV p{anti p} collisions. We measure the top quark mass to be 175.8±6.5 GeV/c2 and the t{anti t} production cross section to be 7.6{sup +1.8}{sub -1.5} pb. We also present measurements of the lifetimes of B-hadrons and the time- dependent B°-{anti B}° mixing which results in the mass difference between heavy and light B°{sub d} mesons ([Delta]m{sub d}) of 0.464±0.030(stat)±0.026(syst) ps−1.

DOWNLOAD EBOOKWe present the latest results on the top quark obtained by the CDF experiment using a data sample of about 110 pb[sup -1]. The data sample has been collected at the FermiLab Tevatron Collider with p[anti p] collisions at[radical]s= 1.8 TeV. We briefly describe the candidate event selection and then discuss the production cross section determination and the mass measurement. Combining the results from the channels with at least one W decaying leptonically into an electron or muon, we measure[sigma][sub t[anti t]]= 7.5[sup+1.9][sub -1.6] pb. Our best measured value for the top mass gives M[sub t]= 176.8[+-]6.5 GeV/c[sup 2]. We also report on the observation of t[anti t] production in the all hadronic decay channel using kinematic selection and b identification, and in the channel containing one hadronically decaying[tau] lepton. Finally we discuss the kinematics of top events and measure the matrix element[vert-bar]V[sub tb][vert-bar]=1.12[+-]0.12.

DOWNLOAD EBOOKThe top quark plays an important role in the grand scheme of particle physics, and is also interesting on its own merits. We present recent results from CDF on top-quark physics based on 100-200 pb−1 of p{bar p} collision data. We have measured the t{bar t} cross section in different decay modes using several different techniques, and are beginning our studies of top-quark properties. New analyses for this conference include a measurement of [sigma]{sub t{bar t}} in the lepton-plus-jets channel using a neural net to distinguish signal and background events, and measurements of top-quark branching fractions.

DOWNLOAD EBOOKThis will be a required acquisition text for academic libraries. More than ten years after its discovery, still relatively little is known about the top quark, the heaviest known elementary particle. This extensive survey summarizes and reviews top-quark physics based on the precision measurements at the Fermilab Tevatron Collider, as well as examining in detail the sensitivity of these experiments to new physics. Finally, the author provides an overview of top quark physics at the Large Hadron Collider.

DOWNLOAD EBOOKThe top quark is by far the most massive fundamental particle observed so far, and the study of its properties is interesting for several reasons ranging from its possible special role in electroweak symmetry breaking to its sensitivity to physics beyond the Standard Model. They present recent top physics results from CDF based on 160-320 pb{sup -1} of p{bar p} collision data at {radical}s = 1.96 TeV. The t{bar t} cross section and the top mass have been measured in different decay channels and using different methods. they have searched for evidence of single top production, setting upper limits on its production rate. Other results shown in this conference include studies of the polarization of W bosons from top decays, a search for charged Higgs decaying from top, and a search for additional heavy t' quarks.

DOWNLOAD EBOOKThe Evidence for the Top Quark offers both a historical and philosophical perspective on an important recent discovery in particle physics: the first evidence for the elementary particle known as the top quark. Drawing on published reports, oral histories, and internal documents from the large collaboration that performed the experiment, Kent Staley explores in detail the controversies and politics that surrounded this major scientific result.At the same time the book seeks to defend an objective theory of scientific evidence based on error probabilities.
